Can someone clarify the terminology here for me? Other than the number of concurrent calls allowed, how is a vPRI different than any SIP service I might buy from my favorite ITSP? Is it because you're using a leased/dedicated/point to point data circuit? Is it because there are many DIDs on one account?
In general, my investigation has found that by the time one pays for a data circuit of sufficient quality and bandwidth to be comparable to a T1/PRI circuit (consider mean time to repair, voice quality etc), that you've spent more than you would on an _actual_ T1/PRI circuit. Further, I assume we all agree that a TDM circuit like this is pretty near the gold standard in terms of voice quality. Am I missing something? What's the driver toward these virtual PRIs?

My apologies Alex... when I said " I was quite sure I was not the only one with Virtual PRI's " -- I meant to say we "use" Virtual PRIs. We do not resell Virtual PRIs, though we should :). We've harnessed vPRI for our office use and know of several vPRI implementations & have done implementations at client side. So to clarify, at this point we do not resell, nor are we affiliated with any organizations to re-sell PRI or vPRI services. Cheers!

I was quite sure I was not the only one with Virtual PRI's :). *For those considering v-pri:* And yes... the ones who know their service is SOLID, will not be afraid to give out test accounts. Most are quick to having you sign a contract... so its important for people in here if they are getting into the VPRI portion to complement their business, to ABSOLUTELY make sure you have tested the service first. While testing... run packet analysis so you know where the traffic is coming from and note your arrival IP for data traffic. If for any reason quality degrades when you have placed your order, run your packet analysis again and see the arrival IP... and if it differs from the test IPs, then you know they put you on a different switch. If they deny you were moved to a different switch - then you know who they are! ;). Cheers!

Most of bells core is now ip :) Virtual pris are wicked when you can get them on a solid network Most people become scepticle of sip channels because certain providers have bad quaility sip trunks, this is a known issue with said providers and its usually due to the fact they are either reselling someone else service or they just have poor networks.. One should always try and sqeek out a test account when selecting a virtual provider and always at least run some programs prior to install like mtr to check for latency accross hops and packet loss to the said providers ip switch and target install location; This will ensure you atleast that your own route to the provider is not gimped.
